1.0 INTRODUCTION

The Water Level Controller System is an Electronic Equipment which when electrically connected to the starter of any given pump -set motor will control the operation of the pump- set depending upon the water level in the Source and Destination Storage Tanks. It Switches ON the Pump-set when Water level drops below pre-set level in Overhead Tank, Switches OFF the Pump-set when Water level in Overhead Tank becomes full ,Switches OFF the Pump-set when Water level is low in tank , and Switches ON the Pump-set when there is sufficient water in the tank.

Automatic water level controller circuit is a engineering project. It can automatically switch ON and OFF the domestic water pump set depending on the tank water level. You can implement this motor driver circuit at your home or college using less costly components. The main advantage of this water level controller circuit is that it automatically controls the water pump without any user interaction.

The automatic pump controller eliminates the need for any manual switching of pumps installed for the purpose of pumping water from a reservoir to an overhead tank. It automatically switches on the pump when the water level in the tank falls below a certain low level, provided the water level in the reservoir is above a certain level . Subsequently, as the water level in the tank rises to an upper level (M), the pump switched off automatically. The pump is turned on again only when the water level again falls below level in the tank, provided the level in the reservoir is above R. This automated action continues.

1.1 ADVANTAGES OF WATER LEVEL CONTROLLER

Advantages of automatic intruder are as follows:

Suitability : These water level controllers are ideally suited for normal water as well as for ultra low conductivity water with less than 1 micro/moh.
Easy to Operate : this systems come fitted with sensitivity setting which can be provided externally on a dial or with internal settings.
Settings : It is equipped with technology which works on low or high sensitivity settings on the same machine and thereby saves costs of buying and using two different machines.
Materials of Construction : this water control system is protected the against corrosion.
Safety : This system is highly insulated, leakage proof and works without creating any noise.

1.2 FEATURES OF AUTOMATIC WATER LEVEL CONTROLLER

1) Automatic Water Level Controller (AWLC) will automatically START the pump set as soon as the water level falls below the predetermined level (usually kept half or 2/3rd tank) and shall SWITCH OFF the pump set as soon as tank is full or water level in the lower tank is at below minimum level.

2) This system provides you the flexibility to decide for yourself the water levels for operations of pump set in upper/lower tanks.

3) Built in Indications for showing Full, Empty Levels in Upper Tank and Lower Tank Empty Indication.

4) Manual operation switch for special operations like watering the plants from pump set.

5) The system ensures no overflows or dry running of pump there by saves electricity and water.

6) Consume very little energy, ideal for continuous operation.

2.1 THE CONCEPT OF WATER LEVEL CONTROLLER SYSTEM:

The Water Level Controller System is an Electronic Equipment which when electrically connected to the starter of any given pump-set motor will control the operation of the pump-set depending upon the water level in the Source and Destination Storage Tanks.
Advanced Automatic “water level controller” unit Manufactured by M.V.Instruments is a Microprocessor based Electronic Device. This system when electrically connected to an Pump-set starter, performs the following functions automatically:

Switches ON the Pump-set when Water level drops below pre-set level (i.e. T2 level) in Overhead Tank.
Switches OFF the Pump-set when Water level in Overhead Tank becomes full (i.e. T1 level).
Switches OFF the Pump-set when Water level is low in Sump/Well/Borewell (i.e. S2 level).
Switches ON the Pump-set when there is sufficient water in the Sump/ Well / Bore-well (i.e. S1 level).
Switches OFF the Pump-set when there is a Dry run (i.e. when Water is not being pumped into Overhead Tank due to any reason).
Low Voltage and High Voltage Protection for the Pump-set is incorporated.
The system has Surge Voltage/Current Protection for the Pump-set.
All these functions are automatically performed. Manual interference is absolutely not required.
Manual operation is also possible if and when required by operating the switch in Manual Position.

2.2 REVIEW OF MANY LOGIC PROBE CIRCUIT IDEAS

Logic probe is useful tool to measure, in check digital circuits. As a meter, this is used to measure power in electrical circuits. Logic probe was used for detection logic “1″ and “0″ or pulse in a digital circuit. It has a handle. At the head of a pin, for measuring different parts of the circuits, or IC pin. At handle has a state of the LED display, as a “1″ or “0″ or pulse. Before use, to connect the two wires to pinch the power supply. To power the internal circuitry. Can be used with TTL and CMOS.I compiled the logic probe types, You can create it yourself is not hard to follow.

Then use Current very low about 10mA by have potentiometer be formed fine the value threshold give just right with the level logic digital both of 3 the level that use by LED1(Green) be the level high and LED2(Red) Be the level LOW and The LED3(Yellow) be the level High IMR . The detail is other please see in the circuit please sir.

2. Mini Logic probe with transistor circuit

This is a Logic probe circuit is one,That is suitable for checking the voltage levels in the TTL circuit. It receives from the circuit being tested.Shows how high or low logic level one.
The circuit when the input voltage to the probe Tip is higher than 2.1 volts (state logic “high”).Transistor Q1 will run the light emitting diodes (LED) LED1 receive direct bias will come out shining. Show the logic “high”(high). When the collector voltage of Q1 running it will fall.and Since the input entered at the end of probe is connected to one end of resistors R4, joint base / emitter of transistor Q2. and Light emitting diode LED2 will get back to bias Q2 and LED2 does not work.
If the input voltage to the late Four home changed to 0 volts (low-level Logistics c), then Q1 is not the current bias is not working.

3. Temple three state logic ic CD4001

The work of the circuit be the circuit will use not gate IC in show supervision. In case of still have no input signal come in be liberate input pin of IC1/1 float keep. Which make have impedance very many, which have no LED anything shine come out.In first condition, If input that come in be “0″ IC1/1 will get back to the position gives output be “1″ make , LED1 switch off . But LED2 the bright condition that pin 5 of IC1/2 be “1″ make pin 7 of IC1/2 be “0″ all the time cause IC1/3 and IC1/4 work give pin 11 of IC1/4 be “0″ make LED3 the bright.
If gush up that come in be “1″ IC1/1 as a result will get back to the position gives output go out be “0″ make LED1 bright the part LED2 switch off IC1/2 receive input be “0″ cause IC1/2 IC1/3 work be frequency signal generator circuit give IC1/4 for current driver give LED3 make LED3 flasher. But if input be pulse signal come in which have signal entireness low and high alternate make LED1 and LED2 stick alternate go to follow the speed of pulse that come in and LED3 condemn bright all the time.

4. LED status TTL logic high low circuit

This is a cycle high or low status of the digital logic signal. Since the 5V power supply is ideal for TTL digital And the circuit to clearly display text. Is easy to see the value.
Operation of the circuit is in normal state or input into Low. And it IC1 to a High state to stimulate Q1 to work with the pressure to drop across R2. That the diodes D1,D2, D3, and connect the LED 7 Segment to display the letter “L” out. If the input is marked High, it makes IC1 return status is Low the Q1 does not work, but will flow from the input through R5, R6 entry. 7 Segment and through R3, R4, D4, D5 to 7 Segment as well. the 7 Segment display letters “H” up. and the cycle will have a resistor R7 is connected with to help reduce the current flow to LED 7 Segment. It prevents damage crash.note: the long time ago I build this circuit with IC TTL 74LS47, but now I can not but this one so I apply to this circuit is very simple and cheap as well.5.
